I'd guess that the volume texture doesn't have mips and these need to change to textureSampleLevel:

bevy/crates/bevy_pbr/src/light_probe/irradiance_volume.wgsl

Lines 45 to 47 in fe777d5

	let rgb_x = textureSample(irradiance_volume_texture, irradiance_volume_sampler, uvw_x).rgb;
	let rgb_y = textureSample(irradiance_volume_texture, irradiance_volume_sampler, uvw_y).rgb;
	let rgb_z = textureSample(irradiance_volume_texture, irradiance_volume_sampler, uvw_z).rgb;
